This article is provided by the Pro Audio Files. Maintaining proper levels throughout your signal chain is important for achieving great tone. This is an important discussion for guitarists and engineers. I think pretty hard about my gain staging when I’m tracking. It has great affect on your sound. But, why and how does gain affect sound? Let’s investigate. 1. Digital Wall There are many reasons to love the analog medium. One, so old guys can sit around the…

When surgeons enter operating rooms at MidState Medical Center in Meriden, CT, they take on two critical roles. Their primary responsibility is patient health, but the second role they have is to demonstrate best practices and procedures in front of a virtual classroom. Two specific operating rooms, the Hybrid OR and the Robot Room, at the medical learning facility enable a global student audience to observe surgical procedures through videoconferencing technology. When Gary Blumberg, Hartford Healthcare collaboration services manager at…

In today’s ever-more-crowded RF environment, wireless system users need every advantage they can get to make sure their show comes off without a hit. While wireless frequency coordination is not a new thing, I find that many in pro audio are unaware of it. This article will explain what it is and what it does, and take you through some scenarios to show how you can benefit from it. Background What’s the core issue? Wireless systems, specifically wireless transmitters, interact…

Kaltman Creations has introduced the new Aaronia PowerLOG horn antenna series, characterized by a broad frequency range and very high input power. The antenna gain increases with frequency up to a maximum of 13 dBi. The PowerLOG 10800 and 70180 are suitable for both transmitting and receiving purposes. Due to the very high maximum transmission power capability the PowerLOG is especially suitable for EMC and immunity test measurements. The antennas include typical calibration data. The 10800 model has a frequency…

Saelig Company has introduced two new RF analyzers—the new AIM-TTi Series 5 Models—available in 3.6 GHz and 6.0 GHz versions. They maintain a true handheld format while offering bench-top instrument-quality features. The PSA3605 and PSA6005 weigh just 560 grams (20 ounces), are small enough to fit comfortably into the hand, and provide more than 3 hours of operation from each charge of the built-in lithium-ion battery. The analyzers incorporate a large high resolution color TFT display with touch screen control.…

Almost every sound system has an equalizer. It can be as simple as a channel strip tone control or as sophisticated as a multi-band parametric. Some view the use of equalization as an art form, while others see it as distinctly technical in application. A prevailing myth is that an equalizer can correct all of the shortcomings of a sound system. Of course this is nonsense, but used properly, equalizers can improve the sound quality and general performance of…

Saelig Company announces the Owon TDS7102, a new 100 MHz four-channel benchtop scope with touch-screen capabilities that make instrument setting, operation, and adjustment faster and more intuitive. With 1GSa/s signal capturing on all four channels simultaneously, a 7.6MSa record length, and 50,000 wfmSa/s capture rate, zooming in and finding fast, intermittent pulses is now much quicker and simpler. Controlling waveform position, display, and triggering is much faster with touch control, but buttons are also provided to offer conventional operation. The…

Since the early 1980s, the term “time alignment” has been tossed around pretty freely, and with dubious degrees of accuracy. Note, however, that this was far from the first time the concept was noticed. Indeed, the engineers who provided the loudspeakers for the first “talkie” film, Al Jolson’s The Jazz Singer, noticed that the “taps” of the tap dancing scenes came out of the high-frequency (HF) horn and folded-horn low-frequency (LF) woofer at different times. Ever since, designers have been…

SynAudCon’s much-lauded “Sound Reinforcement For Technicians” in-person training is coming to Charlotte, NC this coming September 17-19. Sound Reinforcement For Technicians is 3-day multimedia training program that puts learning in the hands of the attendees. The Charlotte sessions will be presented by SynAudCon owner and primary instructor Pat Brown. “When working on sound systems, we need numbers,” explains Brown. “Output level? Impedance of loudspeakers? System polarity? This course is about learning how to take those measurements—and more—and how to interpret…

This article is provided by Audio Geek Zine. When you first look at a synthesizer, it can be a little intimidating with all the knobs and switches and buttons. Believe it or not, most synthesizers have the same blocks of components, and once you figure out what they do, you can pretty much use any synthesizer. The main components you’ll find in a synthesizer: —Oscillators (Red)—Mixer (Pink)—An Envelope Generator (Orange)—LFO (Yellow)—Filter (Green) Additionally you’ll usually find options for: —Polyphony—Arpeggiator—Effects—Ring…
